The reaction of [PtMe2(NN)] and B(C6F5)3/H2O in CF3CH2OH with arenes Ar-H gives [PtArHOB(C6F5)3}(LL)] if the bis(pyridyl) ligand NN forms a six-membered, but not five-membered, chelate ring; methyl-substituted arenes give selectivity for metalation of meta > para > ortho, but methoxy-substituted arenes give ortho > meta, para.
[PtMe2(NN)] 和 B(C6F5)3/H2O 在 CF3C H 中与芳烃 Ar-H 的反应得到 [PtArHOB( )3}(LL)] 如果双(吡啶基)配体 NN 形成六-成员,但不是五成员,螯合环;甲基取代的芳烃对间位 > 对位 > 邻位的金属化具有选择性,但甲氧基取代的芳烃可以使邻位 > 间位,对位。
